11 Claims. (Cl. 144-32) This inventionrelates to a support and jig foruse in aifixing complementary hinge members to blinds and like parts.The main objects of this invention are,

First, to provide a support and a jig designed for use therewith whichgreatly facilitates the application of hinges to sectional blindassemblies and otherhingedly connected parts.

Second, to provide a jig which serves to properly space the members tobe joined and the positioning of hinge members thereon and permits thedrilling of screw holes or bores and the inserting of screws to securethe hinge members to parts to be joined without changing or readjustingthe jig.

Third, to provide a jig having these advantages which serves to properlylocate and support the hinge sections with their knucklesinpintle-receiving alignment.

Objects relating to details and economies of the invention will appearfrom the description to follow. The invention is defined and pointed outin the claims.

A preferred embodiment of the invention is illustrated in theaccompanying drawing, in which:

Fig. 1 is an elevational view of a blind assembly comprising twohingedly connected blinds.

Fig. 2 is a plan View of one of the blind sections,

Fig. 3 is an enlarged fragmentary perspective view of the hingedlyconnected members with a temporary pintle used to facilitate thepositioning of the hinge members.

Fig. 4 is a fragmentary plan view showing the hingedly connected membersof Fig. 3 and their relation to the support forming a part of thisinvention.

Fig. 5 is an enlarged fragmentary View, partially in vertical section,on a line corresponding to line 55 of Fig. 6, illustrating the jig inoperative relation to work and a drill head at the end of its instroke.

Fig. 6 is a fragmentary sectional view on a line corresponding to line6--6 of Fig. 5 illustrating details of the work support and theoperative relation of the jig to the work with the spacers thereof inspacing engagement with the work.

Fig. 7 is a sectional view on a line corresponding to line 77 of Fig. 5,illustrating the hinge supporting magnets, the magnets beingconventionally shown in full lines.

Fig. 8 is an inverted perspective view of the jig with the leaves of ahinge mounted thereon, a work pintle or temporary pintle being shown inengagement with the knuckles of the hinge.

Fig. 9 is a transverse sectional view illustrating the adaptability ofthe jig for the insertion of screws into the bores or holes that havebeen previously formed and without changing the position of the jig.

In the accompanying drawing I have illustrated my invention as adaptedfor use in attaching hinge members to sections 1 of a folding blindassembly, the blind sections being connected by hinges designatedgenerally by the numeral 2. The hinges for mounting the folding blindare not illustrated. The meeting edges of the blind sections haverabbets 3 for providing joint interlapping parts. This is commonpractice in structures of this type.

,United States atnt The hinge designated by the numeral 2 comprises thesimilar leaves 4 having interengaging knuckles 5. The projecting ribportion 6 of one of the blind sections or members is morticed at 7 toreceive the hinge members when the blind sections are positioned asshown in Fig. 1. This is also an old practice.

in assembling the hinges, the sectionsto be hingedly connected arearranged in a support or holder which comprises the bar 8, the holder 9having a downwardly facing hanger hooked over and slidablelongitudinally of the supporting bar.

The holder 9 has a laterally projecting arm lll on which the workengaging member 11 is pivotally mounted at 12. The holder 9 is providedwith an inwardly projecting lug 13 and the member 11 with an opposedinwardly projecting lug 14, the lugs being adapted to engage under thestiles as is illustrated in Figs. 4 and 6.

The jig, designated generally by the numeral 15, comprises a bodyportion having inwardly projecting laterally spaced pairs of spacers 16which project between the work members, as is illustrated, to properlyspace them in hinging relation for the particular hinge that is to beaffixed thereto. These pairs of spacers 16 are spaced longitudinally toreceive the hinge to be attached between them. The jig is provided withholding magnets 17, one for each leaf of the hinge.

When the hinge is positioned on the jig the knuckles thereof areproperly aligned to receive the hinge pintle by the temporary pintle ofpositioning rod 18 which is of such length as to project from the workand is provided with a finger-piece 19 for convenience in manipulation.The jig is provided with guides 26 for the spindles 21 adapted toreceive drills or bits 22 or the shanks of screw drivers, notillustrated. These guides are aligned with the screw holes 23 in theleaves of the hinge.

in Pig. 5 I have illustrated a drill head designated generally by thenumeral 24 and which is provided with four spindles. in commercialpractice a separate screw head is provided for setting or driving thescrews 25 which may be dropped into the guides as is illustrated in Fig.9. The jig is provided with a pair of springable screw supports 26having downwardly converging ends adapted to support the screws inposition for the engagement thereof by the screw driver bits or bladeswhich are inserted in the guides. The ends of these supports are notchedat 27 to properly align the screws with the screw holes in thehingemembers and the bores 28 that have been previously formed by the drillsor bits 22. The centering or guiding notches also provide clearance forthe drills.

With the parts thus arranged the Work can be very quickly mounted on thesupport, the hinge to be attached may be quickly and properly positionedon the jig, the temporary pintle or positioning rod 18 facilitating suchpositioning. The jig is then positioned on the work, such positioningbeing facilitated by the previously formed mortice 7. The work with thejig thereon is then positioned relative to the drill head 24, the holder9 being slidable on the bar 8 facilitating such positioning.

After the holes are drilled the work holder is desirably shifted on thebar 8 to position the jig in proper relation to a screw driving head,not illustrated, the screws being dropped into the guides after the jighas been shifted from below the drill head. The mechanism described isduplicated where two hinges are to be applied as is the most commonpractice. This arrangement enables a very rapid and accurate applicationof the hinges to the Work. The hinge members are uniformly applied sothat it is not necessary that the same blind sections be used inassembling a blind unit, which greatly facilitates the various otherfinishing, handling and shipping operations.
